发动机实时建模技术的新发展

THE UP-TO-DATE DEVELOPMENT OF AEROENGINE REAL-TIME MODELLING

本文从发动机控制的角度，对国内外近十几年来发动机实时建模技术的研究成果作了概要综述，评述了几类实时建模的方法，特别是自适应技术在机载实时模型建模过程中的应用，并指出将来实时模型的主要发展方向是自适应模型和智能化建模技术。

This paper overviews the research achievements of aeroengine real-time modelling in the light of aeroengine control,in recent ten years in our country and abroad.Several kinds of modelling methods,such as simplified component level model,state variable model and online real-time model,are intruduced.Emphasis is put on the application of adaption technology to the online real-time model,and three typical adaptive models.The trend of the aeroengine real-time models is the application of adaptive model and intelligent modelling.
